The pizza shop is running a special: 2 medium pizzas
for $6.99 each. How much would it cost to by 12
pizzas?
Answer:
41.94
Step-by-step explanation:
12 divided by 2 is 6 and six times 6.99 gets you your answer of 41.94
Answer:
$72.00
Step-by-step explanation:
Lets round $6.99 to $7.00. Now we have an easier number to work with.
To find the total price of 12 , we need to multiply $7.00 by 12.
⇒ $7.00 x 12 = $84.00
Since we added 1 cent to $6.99 and multiplied by 12, we need to sutract 1 times 12.
1 x 12 = 12
$84 - $12 = $72.00

Find the x and y intercept of the following equation 4x-10y=20
For the given linear equation we have:
y-intercept: y = -2x-intercept: x = 5.How to find the intercepts for the linear equation?Here we have a linear equation:
4x -10y = 20
First, let's find the y-intercept, this is the point with x = 0, so evaluating in that we get:
4*0 - 10y = 20
-10y = 20
y = 20/-10
y = -2
The x-intercept is what we get by evaluating in y = 0.
4x - 10*0 = 20
x = 20/4
x = 5

A is directly proportional to the square root of B
When A = 50, B+4 . Find A in terms of B
Answer:
A=50, B=4
A is directly proportional to the square root of B
name the constant 'k'
A = k*B^0.5
50 = k*4^0.5
50=2k
k=25
=> A =25 root B
i.e, A = 25*B^0.5 (The answer should be written the way it is written in the attached picture)
A written in terms of B is 25√B.
What is direct and inverse proportion ?In direct proportion if one quantity increases the other quantity also increases and vice versa.In case of inverse proportion when one quantity increases the other quantity decreases and vice versa.
According to the given question A is directly proportional to the square root of B.
∴ A = K[tex]\sqrt{B}[/tex]
Given when A = 50 B = 4.
50 = K[tex]\sqrt{4}[/tex]
50 = 2k
k = 25.
So, A =25√B.

New York City is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 3 vans and 14 buses with 509 students. High School B rented and filled 12 vans and 10 buses with 472 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
Answer:
Step-by-step explanation:
Let's say :
v = number students in van, b = number of students in bus
From the info provided in the question:
High school A takes 3 vans and 14 buses for 509 students
We can write this as:
3v + 14b = 509
You can re-write this as :
3v = 509 - 14b
We also know High School B takes 12 vans and 10 buses for 472 students:
12v + 10b = 472
Since we already know that 3v = 509 - 14b , substitute this equation into the above formula and you get:
12v + 10b = 472
4(509 - 14b) + 10b = 472
2036 - 56b + 10b = 472
2036 - 46b = 472
2036 - 472 = 46b
1564 = 46b
Divide both sides by 46 to find "b".
b = 1564/ 46 = 34
Therefore the number of students that fit in each bus is 34.
So since we know b = 34, substitute b into the equation at the top:
3v = 509 - 14b
3v = 509 - 14(34)
3v = 509 - 476 = 33
Divide both sides by 3 to find "v".
v = 33/3 = 11.
Therefore the number of students in each van is 11.
